Rilutek® (Riluzole tablets), the first ALS drug ever approved by the FDA for the treatment of ALS, is on the market. This glutamate-blocking drug has been proven effective in well-controlled studies using survival as an end point. The most common side effects of Rilutek® are weakness, nausea, lung function decrease (not associated with a reduction in vital capacity), a mild liver disorder that is typically temporary and headache.
Gene therapy research programs in neurology within R-PR have been discontinued. There are no ALS clinical trials being conducted by R-PR at this time. However, future trials are not precluded.
In response to an article titled "New ALS Drug Riluzole Causes Liver Problems," published early in 1999 in Hepatitis Weekly, RP-R spokesperson Sheryl Williams provided the following statement: "Patients currently on or considering starting Riluzole should not be overly alarmed by this article. The possibility of adverse effects of Rilutek on the liver is well known and the physician who prescribes this drug is carefully advised of the potential problems.
The possibility of liver injury is discussed in the "Warnings" section of the product's labeling. Although that labeling does not specifically discuss hepatitis, it recommends that any patient being prescribed Rilutek receive tests of liver function prior to and during therapy. These tests will allow the physician to determine if the liver is reacting badly to Rilutek and to respond early if a problem occurs. …
The labeling also states: "Maximum increases in serum ALT usually occurred within 3 months after the start of Riluzole therapy and were usually transient when less than 5 times the upper limit of normal. In trials, even when ALT levels were less than 5 times the upper limit of normal, treatment continued and ALT levels usually returned to below 2 times the upper limit of normal within 2 to 6 months…."
